The mean testicular SWVQ using the ARFI shear wave technique was a reliable, non-invasive and acceptably stable method for predicting male infertility, especially related to sperm count issues.

Background Degenerative change in articular cartilage is one of the most important factors in the development of osteoarthritis. Shear wave elastography can be used to identify pathologic cartilage. Purpose To evaluate distal femoral cartilage by shear wave elastography in patients with symptomatic knee osteoarthritis. Material and methods Twenty patients with bilateral knee osteoarthritis (study group) and 20 volunteers with the same demographic characteristics but without symptomatic knee pain (control group) were included in the study. A total of 80 knee joints of 40 individuals were evaluated. At the medial, intercondylar, and lateral condylar levels distal femoral cartilage thickness was measured by B-mode ultrasonography and stiffness was measured by shear wave elastography. Results The medial, intercondylar, and lateral cartilage thickness measurements were similar between the two groups and no statistically significant difference was observed ( P = 0.711, P = 0.766, and P = 0.575, respectively). The shear wave velocity values in the medial and intercondylar cartilage were significantly higher in the study group ( P = 0.002). Shear wave velocity values measured from lateral cartilage were higher in the study group and the difference between the groups had a borderline statistical significance ( P = 0.053). Conclusion Shear wave elastography seems to be a reliable, non-invasive, and acceptable method for the assessment of pathologic cartilage.

This study aimed to examine the testicular functions with sperm analysis of patients with COVID‐19. The study was carried out with male patients aged between 18 and 50 years with positive RT‐PCR test and SARS‐CoV‐2 virus between December 2020 and April 2021. A total of 103 participants were included in the study. The mean age was 31.24 ± 5.67 (19–45) years and the mean body mass index of the participants was 28.41 ± 4.68 kg/m2. The patients were divided into two groups, group‐1 was patients who had COVID‐19, group‐2 was healthy men. A semen analysis of both groups was performed, and the serum total testosterone, FSH, LH, anti‐mullerian hormone and Inhibin‐B tests were analysed and recorded. The testicular dimensions and testicular densities were examined by ultrasound and elastography for both groups. Comparing the patient and control groups results, this study found that the sperm count per 1 cc (p = 0.01) and total motility (p = 0.01) in group‐1 was lower than in the control group, the testicular dimensions decreased (for right testis group‐2 was 15.39 ± 4.78 ml versus group‐1 was 12.11 ± 4.62 cm3 p < 0.01, for left testis group‐2 was 16.01 ± 5.12 versus group‐1 was 11.92 ± 4.78 cm3; p < 0.01), and the shear wave velocities were significantly higher in group‐1 patients. In conclusion, sperm parameters deteriorate in men who have symptomatic disease with SARS‐CoV‐2 infection. The fact that the cause of this deterioration is characterized by changes at the cellular level in the testis raises doubts about the persistence of this condition.

SummaryBackgroundArachnoid cysts are congenital, benign and intra-arachnoidal lesions. A great majority of arachnoid cysts are congenital. However, to a lesser extent, they are known to develop after head trauma and brain inflammatory diseases. Arachnoid cysts are mostly asymptomatic and they can develop anywhere in the brain along the arachnoid membrane.Case ReportArachnoid cysts form 1% of the non-traumatic lesions which occupy a place and it is thought to be a congenital lesion developed as a result of meningeal development abnormalities or a lesion acquired after trauma and infection. There is a male dominance at a rate of 3/1 in arachnoid cysts which locate mostly in the middle fossa. Our patient was a 2-years-old boy.ConclusionsAs a conclusion, spontaneous subdural hygroma is a rare complication of the arachnoid cysts. Surgical intervention could be required in acute cases.

Background Idiopathic granulomatous mastitis (IGM) is a chronic, unpleasant autoimmune inflammatory condition and is clinically and radiologically often confused with breast malignancy. Purpose To investigate the contributions of qualitative and quantitative aspects of acoustic radiation force impulse (ARFI) elastography to the differential diagnosis between IGM and invasive ductal carcinoma (IDC) in the breast. Material and Methods Ninety-four women with IDC and 39 with IGM were included in the study. Shear wave velocity (SWV) was calculated for all lesions using quantitative elastography. Next, each lesion’s correspondence on qualitative elastographic images to those on the B-mode images was evaluated: pattern 1, no findings on elastography images; pattern 2, lesions that were bright inside; pattern 3, lesions that contained both bright and dark areas; and pattern 4, lesions that were dark inside. Pattern 4 was subdivided into 4a (dark area same size as lesion) and 4b (dark area larger than lesion size). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated. Results The mean SWV based on ARFI elastography was 3.78 ± 1.26 m/s for IGM and 5.34 ± 1.43 m/s for IDC lesions ( P < 0.05). Based on qualitative ARFI elastography, IDC lesions were mostly classified as pattern 4b, while IGM lesions were mostly classified as pattern 1 or 2 ( P = 0.01). Evaluation of both the qualitative and quantitative aspects of ARFI elastography yielded a sensitivity of 89% and specificity of 84%. Conclusion ARFI elastography may facilitate the differential diagnosis between IGM and IDC.
